Umbilical termination assembly (UTA)
Subsea UTA on a skirted mudmat: square-tube frame with lift points, grab bars and anodes; umbilical termination head bolted to a bulkhead frame, vertebrae bend restrictor dropping to the seabed and an umbilical stub lying on the seabed to its cut end. ROV panel with a fixed MQC stab plate (couplers) carrying a mated flying MQC half with ROV handle and bucket, its hydraulic flying lead running to a parking bracket on the mudmat; wet-mate electrical receptacles with dust caps (electrical) plus one mated electrical jumper parked on a second bracket. Internal tubing and cables run from the head to the plates. y = 0 is the seabed.
Installation
Copies drilling/umbilical-termination-assembly.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.
Usage
import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { UmbilicalTerminationAssembly } from './components/deck-twin/drilling/umbilical-termination-assembly'
export default function Scene() {
return (
<Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
<Stage>
<UmbilicalTerminationAssembly />
</Stage>
<OrbitControls makeDefault />
</Canvas>
)
}

P&ID
On subsea control schematics: the umbilical (a thick double line or bundle) ending at a termination head inside a dashed structure, fanning out to hydraulic, chemical and electrical couplers that connect by flying leads to trees and manifolds.
A structure where the umbilical bundle splits into many small hydraulic / electrical lines is a UTA or SUTU; one carrying production pipework is a manifold or PLET.

For agents
Machine-readable entry with props, ranges, defaults and ports:
Or fetch /r/umbilical-termination-assembly.json, or copy a ready-made instruction:
Add the Deck Twin "Umbilical termination assembly (UTA)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add umbilical-termination-assembly` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info umbilical-termination-assembly` for its props, ranges and ports. Render <UmbilicalTerminationAssembly /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
